How to make a fluid simulation start from the middle of an animation and make the domain not visible until that point?
in the domain, change the frames from 0 to 250 (or however your flow simulation lasts)
do not keyframe inflow type (delete those keyframes)
do keyframe use flow (74 - off, 75 - on)


4) free bake and bake all

visibility:
the domain itself normally is not visible, but the effector might be visible.
you can keyframe the visibility of objects here:
